Description

本発明は食用油脂組成物、特に加熱調理に適した食用油脂組成物に関する。   The present invention relates to an edible oil / fat composition, and particularly to an edible oil / fat composition suitable for cooking.

食用油脂の主な用途は、揚げ物、炒め物等の加熱調理であり、加熱調理の際に生じる臭気(加熱臭)の抑制が、家庭用業務用を問わず作業環境改善の面で求められて来た。また、消費者の嗜好としても、あっさりとした風味が好まれる傾向にある。加熱調理に使用される食用油脂は、精製工程の改善により、より雑味が取り除かれている。また、近年では、酸化安定性に強く加熱臭の少ない高オレイン酸系の植物油脂が市場に浸透している。   The main use of edible oils and fats is for cooking foods such as fried foods and fried foods, and the suppression of odors (heated odors) produced during cooking is required in terms of improving the work environment regardless of household use. I came. In addition, consumers tend to prefer a light flavor. The edible fats and oils used for cooking are removed from the miscellaneous taste by improving the refining process. Further, in recent years, high oleic acid vegetable oils and fats that have strong oxidation stability and little heating odor have penetrated the market.

食用油脂の加熱臭を抑制するために、例えば、高温での脱臭が行われうる。しかしながら、高温での脱臭は、健康に良くないとされるトランス脂肪酸を生じるので、好ましくない。特開2007−14263号公報には、薄膜式カラムを用いた精製処理とトレイ式装置を用いた精製処理とを組み合わせて、全構成脂肪酸中のトランス脂肪酸含量が1質量%以下の油脂を精製する工程が開示されている。しかしながら、上記工程は複雑であり、コストが高い。   In order to suppress the heating odor of edible fats and oils, for example, deodorization at a high temperature can be performed. However, deodorization at high temperatures is undesirable because it produces trans fatty acids that are considered unhealthy. Japanese Patent Application Laid-Open No. 2007-14263 refines fats and oils having a trans fatty acid content of 1% by mass or less in all constituent fatty acids by combining a purification process using a thin film column and a purification process using a tray type apparatus. A process is disclosed. However, the above process is complicated and expensive.

また、食用油脂の加熱臭を抑制するために、各種の添加剤が用いられる。国際公開第2001/096506号には、アスコルビン酸、エリソルビン酸及びリンゴ酸の中から選ばれた少なくとも1種の有機酸を2〜28ppm含有する、加熱臭が改善された油脂が開示されている。しかしながら、有機酸は熱分解が速く、効果が持続しない。また、特開2009−50234号公報には、0.1〜10.0ppmのリン分を含有する加熱耐性に優れた揚げ物用油脂組成物が開示されている。しかしながら、当該組成物は、加熱臭を改善する効果に乏しい。   Moreover, in order to suppress the heating odor of edible fats and oils, various additives are used. International Publication No. 2001/096506 discloses an oil and fat with improved heating odor, containing 2 to 28 ppm of at least one organic acid selected from ascorbic acid, erythorbic acid and malic acid. However, organic acids are rapidly pyrolyzed and the effect is not sustained. Japanese Patent Application Laid-Open No. 2009-50234 discloses an oil and fat composition for deep-fried foods having a phosphorus content of 0.1 to 10.0 ppm and excellent in heat resistance. However, the composition is poor in the effect of improving the heating odor.

したがって、食用油脂の加熱臭を効果的に抑制する簡便な方法の開発が望まれていた。   Therefore, development of a simple method for effectively suppressing the heated odor of edible fats and oils has been desired.

解決しようとする課題は、食用油脂の加熱臭を抑制する簡便な方法を開発することである。また、加熱臭の抑制された食用油脂を開発することである。   The problem to be solved is to develop a simple method for suppressing the heating odor of edible fats and oils. Moreover, it is to develop edible fats and oils with suppressed heating odor.

本発明者らは、上記課題を解決するために鋭意検討を重ねた。その結果、食用油脂が極微量の米ぬか油抽出物を含有することにより、本課題が解決できることが見いだされた。これにより、本発明が完成するに至った。   The present inventors have made extensive studies to solve the above problems. As a result, it was found that this problem can be solved when the edible fat contains an extremely small amount of rice bran oil extract. As a result, the present invention has been completed.

More specifically, the rice bran oil extract can be extracted with a solvent from, for example, a soda oil cake further saponified with an alkaline solution. Moreover, the rice bran oil extract can be extracted with a solvent from, for example, deodorized scum obtained by alkaline deoxidization of free fatty acids. The solvent may be one or more selected from hexane, acetone, and ethanol, and is preferably hexane. The rice bran oil extract that has been solvent-extracted and desolvated may be purified by decolorization, deodorization or the like.
